Harmonix, EA and MTV have now officially announced Rock Band 2, dated for release in only a few months time this September for North America on the Xbox 360. Given how neglected Australia has been on the first game (the one that was released in November 2007 in North America) we'd advise not to hold your breath too long for this one.

Nevertheless, here's the points of note from the press release:

• Backwards compatibility with Rock Band downloadable music content. All previously purchased tracks will immediately load into your Rock Band 2 song list. No need to re-purchase or re-download.
  
• The biggest and most diverse soundtrack ever featuring some of rock’s most prolific acts, comprised entirely of master recordings.
  
• Major new and dynamic online modes that will connect the entire Rock Band community in more ways than ever before both locally and globally.
  
• More variety of instrument choices than ever before with new and improved drum and guitar peripherals, enhanced functionality and innovative new designs - all fully compatible with the original Rock Band instruments.

Interestingly, the Xbox 360 version will enjoy a short period of exclusivity, with other platforms to follow 'later in the year'. Perhaps another jab in our ribs, as like the original Rock Band, it will most likely be region locked to prevent importing - unlike the region free PlayStation 3 version.
